Probing fermionic asymmetric dark matter cores using global neutron star properties Open
It is possible for asymmetric dark matter (ADM) to accumulate in neutron star interiors and affect their global properties. Considering the effects of this accumulation, neutron star mass-radius measurements can deliver new insights into t…
